Abstract

By drilling a large number of experiments, the drilling force, bit positioning error and other data, Using high resolution camera and microscope observation techniques to obtain microdrill digital photos, based on the structural analysis of micro drill, the stress model is established, Based on the combination of experimental research and theoretical calculation, the combination of quantitative and qualitative analysis. The fracture mechanism of micro drill is defined from three aspects, such as the fracture observation of micro drill, the calculation of ultimate stress and the calculation of stress cycle .The results show that the fracture of micro drill is that the drilling force reaches the strength limit of the material, which leads to the failure of the static strength.
